At the time of this encounter, I had been married to Roger, my first husband for approximately four years. It was eight O'clock on a Saturday evening when I heard a knock on our front door. I answered to find a young woman in her early twenties, who introduced herself as Susan.

Susan informed me that she and her husband, Mark had just moved into a house in our street and were having a housewarming party that evening for the neighbours and some of their friends. She apologized for the short notice but explained that the party hadn't been planned until earlier that day.

I thanked Susan for her invitation and invited her in, but she declined and explained that she still had a few more doors to knock on and also had to rush back home to organise things.

Roger wasn't very impressed when I told him about the party invitation.

"Sure you know that Les, Dave and Chris are coming round at nine O'Clock to watch footy and have a few drinks. You can go by yourself if it's that important to you,"

I thought about it for a while and decided to go to the party without Roger. I didn't like watching football on television anyway and usually went into the sitting room to listen to music when Roger and his friends were watching football.

I took a quick shower and got dressed. Black leather skirt, cupless bra, black lace top, stockings, a skimpy g string and my new leather boots with a four-inch heel. I ran downstairs, put on my black denim jacket and left by the back door, just as Roger was opening the front door to let his friends in.

Susan's house was only about fifty yards from my house. Some of my neighbours were standing in the front garden, talking and smoking. Susan was standing in her hall with a glass of wine in her hand while talking to a young man. She smiled at me and said. "Hi Kate, come on in."

Susan introduced me to the young man, who was her younger brother, Adam, and was eighteen. Susan was very busy so she asked Adam to show me around and get me a drink and something to eat.

Adam and I made our way to the kitchen where Susan's husband, Mark was in charge of serving food and drinks to the guests. It seemed like most of my neighbours had turned up and had descended on the kitchen like a plague of hungry locusts.

Adam asked me what I would like to drink and I asked him if he could get me a gin and ice. He poured about half a pint of gin into a pint glass and filled it to the brim with ice. He took a couple of bottles of Budweiser and we left the crowed kitchen.

Adam then started to give me a tour of the house. Mark had extended the lounge and fitted French doors, which led into a barbecue area in the back garden. He then took me upstairs to show me the new bathroom layout with a new jacuzzi and a walk-in shower.

Adam told me that he would be living with Mark and Susan for about six months and that he was using the two rooms in the new attic conversion to live in, while he was staying there.

"Let's check them out now, Adam. I'm dying to see what an attic conversion looks like in these houses. Maybe I could get Roger to convert our attic?"

We made our way upstairs and through a door which revealed what could be best described as a fair-sized self-contained flat with a door that led to an adjoining En-suite bedroom. There was a large dormer window that let lots of natural daylight into the room and when I looked through it I realized that it gave an uninterrupted view of my back garden, which was just four doors away.

I pointed out where my back garden was to Adam, who was standing behind me and he said that he knew where it was and that he had seen me sunbathing there a few times.

Adam said, "You don't wear much, do you?"

"I don't wear anything as you are no doubt very aware"

Adam put his arm around me from behind and pulled me tightly to him, while kissing my neck I could feel his hard cock pressing into me and I instinctively reached down with my left hand to touch it. Even through his jeans, I could feel that it was very long and thick. I fumbled with his zipper and was able to get my hand inside his jeans and grasp the thick shaft of his cock.

I turned around and faced Adam, before kneeling in front of him. He dropped his jeans and after setting my drink down on the floor, I started licking and kissing his cock, before wanking it with my lips.

After a few minutes, Adam suggested that we should go into the bedroom, where we could be more comfortable. I spat out his cock and said,

"Fine, by me, but I'll run downstairs and get some more ice in this gin first."

My glass was only about a quarter full and I was feeling rather shaky as I made my way back downstairs and into the kitchen. Mark topped my glass up with gin and I filled it with ice cubes. On my way back to the attic, I passed Susan in the hall and she asked me if I was all right. I just giggled and made my way upstairs, sipping my drink as I went.

Back in the Bedroom, I found Adam lying naked on the bed, gently stroking his rigid cock. I took off my blouse and skirt and assumed a soixante-neuf position over Adam, grinding my pussy down hard on his mouth, as I started giving him some serious deep-throating.

Adam was moaning as I bobbed my head up and down on his erection. I managed to swallow it so deeply that his balls were tight against my lips at times, but although Adam was doing his best to please me, I wasn't getting anywhere near an orgasm. I needed a cock inside me urgently.

I let Adam's cock go and slid forward on the bed until I was able to get into a reverse cowgirl position. My pussy was well lubricated from Adam's tonguing efforts and his cock slid inside me without any effort.

Adam's cock was a good inch longer than my husband's cock, but it was much thicker. It felt so different as I rode on it and I was really enjoying the experience. Adam was pushing his cock deeply into my vagina and I knew that if I clenched tightly on him, I could have made him cum within a few seconds.

I reached over to the bedside table where I had put my drink and just as I was taking a sip, while sitting straight up, the bedroom door opened and there stood Susan with a huge grin on her face.

Susan closed the bedroom door and as she walked toward us she said,

"I see that you and Adam are getting to know each other."

Susan placed her right hand on my exposed breast and then leaned forward to kiss me. With her left hand, she started undoing the buttons on her blouse. I helped her as both my hands were free and within seconds, Susan was topless and it was my turn to caress and kiss her breasts.

Susan reached down and played with my clit as we kissed. Adam didn't seem to be bothered by his sister joining in and he kept fucking me at a steady pace.

Then Susan turned around and took off her leather skirt and her sexy little G string. She stood there, naked, apart from her hold-up stockings. I hoped that she didn't have a hairy pussy, but when she turned to face me, I was in for the surprise of my life, because Susan had a cock that was almost as long and as thick as her brother's cock. She was the most convincing T-Girl who I had ever seen

Susan asked, "Will you suck me off?"

Without answering, I disengaged from Adam's cock and got on my knees on the bed, while Susan held my head and fed her rigid penis into my mouth. Adam got behind me and buried his cock deep inside my pussy and started fucking me hard and deep. I was gasping and gagging at the same time, as Susan forced her cock down my throat.

I suddenly felt Adam's cock tense up and a few seconds later, he emptied his hot load of cum, deep inside me. I was on the point of orgasm when Susan ejaculated into my throat. I gagged on it but managed to swallow every last drop. Susan withdrew her cock from my mouth and Adam released me and got off the bed, however, Susan sensed that I hadn't yet achieved an orgasm and flipped me over onto my back, before going down on me to tease my inflamed clit with her tongue. That did it and I had one of the most amazing orgasms of my life.

There was silence for a while, apart from heavy breathing until Susan stood up and said.

"Better get dressed, Adam, we'll be expected downstairs."

Adam left first and Susan tidied herself up in the en-suite bathroom. Her chin and lips were covered with Adam's sperm and my juices. Before she left, she kissed me and told me that the next time I visited, she wanted my ass.

I took a quick shower, before getting dressed and left soon afterwards. When I got home, Roger and his three friends were still watching football. They didn't even notice me coming in. I went upstairs, got undressed, got into bed and was asleep within seconds.
